When shopping for value, Consumer Reports recommends comparing costs by the number of square feet per package, factoring in you’ll likely use less sheets with multi-ply rather than single ply. But don’t assume comfort increases with the count; most claims of “ultra-strong” or “extra-soft” are null, as are sizes like “jumbo” or “mega-sized.” Bulk packaging doesn’t always imply a better deal, so study the price-per-roll sticker at supermarkets or whip out your phone calculator to ensure there’s actually a bargain. Finally, aim for environment-friendly choices made from recycled papers and septic-safe options that dissolve easily to avoid a costly headache down the road. To buy: $6 for 12 rolls; walmart.com.
